Specification of Letters Patent.

Patented J an. 2, 1912.

To all'whom it may concern:

Be it known that I, ARTHUR Annnio'r Form, of Brooklyn, New York, in the State of New York, one ofthe United States of America, designer, have; invented certain new and useful Improvements in Rowing- Machines; and I do hereby declare that the following is a full, clear, and exact description of the same.

The invention. relates to improvements in rowing machines as ent specification and illustrated in the accompanying drawingsthat form part of the same.

The invention consists essentially in the novel construction and arrangement of parts, whereby the weight of the stroke is compensated by resilient elements attached to the seat and oar handles respectively in a readily removable assemblage of parts.

The objects of the invention are to; provide an exercising machine of this type in which the operator can see at a glance the amount of exercise he has done, to provide a machine with which exercise may be obtained for both body and arms simultaneously and generally to provide a rowing machine durable, portable, simple in construction, cheap to. manufacture and whose parts are readily accessible for renewal if necessary.

In the accompanyi g drawings Figure 1 is 'a perspective view of the machine and a floor broken away. Fig. -2 is a perspective view 'of a joint in the frame of the machine.

Like numerals of reference indicate corresponding parts in each of the figures.

Referring to the drawings, 1 is the base frame of the machine, comprising longitudinal bars 2 and 3 and transverse bars 4 and '5 "all preferably rectangular in cross section and joined together in any suitable manner but preferably by the well known interlocking joint illustrated in Fig. 2. With the use of this joint the frame may be assembled or disassembled in avery short time as the said bars are not fastened together yet form a rlgid frame when assembled. 6 are grooves cut in the outer side faces of the longitudinal bars and 3 extending from the rear ends of. said bars to a point intermediate of the length thereof.

Application filed February 8, 1911. Serial No. 607,336.

described in the presends of said levers takes hold of the rowing levers 13 the seat slides forward through the'wheels' 9 rolling along the'lon- 7 and 8 are parallelly arranged axles, upon the extremities of which are rotatably mounted the flanged wheels 9.

10 is a seat resting across the axles 7 and 8 and suitably clamped thereto on the underside, thus providing a liding carriage with flanged wheels adapted to roll along the longitudinal bars 2 and 3, the flanges retaining and guiding said carriage in its movement. f

11 are curved arms rigidly secured to the ends of the forward axles 7 outside of the wheels 9 and extending downwardly to the grooves 6. j

12 are coiled springs lying within the grooves 6 and having their one ends connected to the extremities of the curved arms 11, their other ends being secured to the ends of the longitudinal bars 2 and 3.

13 and 14 are rowing levers respectively mounted upon the longitudinal bars 2 and 3 near the forward ends thereof, the outer being connected to said bars by ball and socket join-ts.

15 are hooks screwed into the levers 13 intermediate of the length thereof.

16 is an indicating device secured to the wall of a building and 17 is vice arranged int-he path of the finger 18 of said indicating device and operated each time said finger passes thereunder.

19 are sprlngs having their one ends caught onto the hooks 15-and their other ends connected to a loop 20 forming a connection between said springs and the indicating device 16.

The indicating and counting devices have not been described in detail herein as the same form no part of this invention an any such devices may be used either separately or together.

21 'are foot rests obliquely secured to the transverse bar 4 b the blocks 22.

23 are straps a apted to be secured over the feet of the operator to retain same on the footres'ts 21.

In the use of this machine the operator sits upon the seat 11 with his feet held. to the foot rests 21 by the straps 23.. He. then with the result that gitudinal bars 2 and 3 thereby stretching the springs 12 which provide a resistance to the and pulls,

a counting deforward movement of the seat. Simultaneously with the forward movement of the seat,the rowing levers are pulled toward the operator the springs 19 being stretched and providing a resistance to the movement of said levers, while the said springs being .connected to the indicating device the finger 18 thereof will be moved over v the dial, indicating the amount of the pull.- Each time the finger 18 passes the counting device 17 it will be recorded thereon so that the operator may see at a glance the exact amount of work he ha'sdone, namely the strength of the pull and the number of pulls.

' One of the chief features of this machine is that the operator will obtain beneficial exercise both to the body and the arms, the

springs 12 providing the necessary resistance for the former and the springs '19 for the latter. I

The details of construction may be modified 'to some extent so long as the main features are retained as set fort-h and claimed in the several claims for novelty hereinafter.

lVhat I claim as my invention is: Y

1. In a rowing machine, a frame comprising longitudinal and transverse bars,-a carof rowing .levers mounted at the front of riage slidable on said longitudinal bars,

means for resiliently resisting the sliding of said carriage in a forward d1rect1on, a palr said longitudinal bars and means for resiliently resisting the rearward movement of said levers.

2. In a rowing machine, slidable on the rear end of pring held rearwardly,

said frame and and a pair of row- I ing levers movablymounted on the forward end of said frame. a

3. Ina rowlng machine, a frame comprising detachable longitudinal and transverse bars, a pair of parallelly arranged axles, Wheels rotatablymountedon the ends of said axles and adapted to roll on saidlongitudinal bars, a seat mounted on said axles,

means resiliently connecting one of said axles with the rear end of the frame, a pair of rowing levers pivotally mounted on the front end ofsaid frame,

in front of the machine and springs cona frame, a seat.

an indicating device rigidly secured to a stationary ,structure necting said indicating device with said rowing levers. v

In a rowing machine, a frame comprising longitudinal and transverse bars detachably united, "a pair of parallelly arranged axles, flanged wheels rotatably mounted at the ends of said axles and adapted to vroll on said longitudinal bars, a seat mounted across said axles, curved arms rigidly secured to the ends of one of said axles, springs having their one endssecured to the curved arms aforesaid, and their other ends to the rear ends of said longitudinal bars, a pair of-rowing levers mounted with balland socket joints upon the front ends of said longitudinal bars respectively, an indicating device rigidly secured to a stationary structure infront of the machine and springs resiliently connecting said rowing levers with said indicating device.

5. In a roWin machine, a frame comprising longitudina and transverse bars, said longitudinal bars having grooves in their outer side faces extending from the rear end toward the front thereof, a pair of parallelly arranged axles, flanged wheels rotatably mounted at the ends of said axles and adapted to roll on said longitudinal bars, a'seat mounted upon said axles, curved arms extending downwardly from the ends of=one of said axles, springs lying in said grooves and having their one ends secured to the curved arms aforesaid, and their other ends Signed at the borough of Brooklyn, New I York, N. Y., U. S. A, this tliird day of Febi ruary 1911.
